The responding trooper said Sgt. Kevin Meyer, 50, of Winter Garden, was in uniform and was unsteady on his feet, had slurred speech and was acting suspicious.

The trooper said his eyes were bloodshot, he smelled of alcohol and his face was flushed red.

The second driver told troopers she was traveling on County Road 535 when she noticed the vehicle with its emergency lights on, so she tried to pull over. Before she could stop, she was hit from behind.

After the crash, she said Meyer began acting suspicious and allowing witnesses to leave without getting their information.

A trooper began to give Meyer a series of field sobriety tests, but he refused to continue after the one of the tests, FHP said.

On the dash camera video, Meyer can be heard asking the trooper if he was required to do the tests.

"I can't make you do them, no," said the trooper on the video. "Does that answer your question?"

"I'm not going to do them," Meyer said on the video.

He was arrested and later refused to give a breath test, according to FHP.

"Based on what I've seen and the smell of alcohol on your breath, I'm going to place you under arrest for DUI," the trooper said on the video. "Please turn around and put your hands behind your back."

The investigating trooper said a Powerade bottle was found in his vehicle with a pink liquid that smelled like alcohol.

Meyer is a 23-year veteran with the department and was assigned to the OCSO tactical unit.

Those duties are suspended, and he has been reassigned to administrative work pending the outcome of the charges, the Sheriff's Office said.
